Question

Suppose you are given n sets:S1,S2.....Sn each set is having n elements.the problems is to find whether some pairs of these sets are disjoint,i.e. there are no common elements in these sets.write pseudo code and calculate its time complexity.

Answer 1

Start
Scan elements A[n], B[n]
for loop initiated i to n
  for loop initiated j to n
      if(A[i]==B[j])
        Set is not not a disjoint
      else 
        set is disjoint
stop

Time complexity of the code $T(n)=O(n^2)$
